Longwood House Long Barrow near Winchester, Hampshire

What does one say about a site like this? Another of Hampshire’s “lost” Long Barrows. Unvisited, unloved and almost inaccessible later in the growing season because of the waist high stinging nettles. Partly trashed in the past by a small quarry at the NW end and a track over the centre and rabbit/badger burrows at the SE end. Photographic recording of sites like this is important, boring though the images may be, as ancient barrows like this can so easily be lost.

As a case in point, my old (1976) 1: 25,000 OS Map (SU42/52) shows clearly a fenced Long Barrow a couple of hundred meters to the SE.
Later maps and a site visit show no traces. What has happened to it in the past 30 years?

Access Private woodland but footpaths close by.
